Jet Drivetrain products

[Trailblazin]

I looked into their site and found they have alot to offer fot eh 4L60-E and if i'm not mistaken is the same transmission that we use! So the matter at hand is, would these mods help us out in anyway!? Has anyone installed these already?? I noticed Project Sonic had more then the Jet Chip module, so would love to see the other thing he had installed.

Here's a couple links of what I've seen:
